Usually a person is going to be interviewed by a few individuals and groups and it's fair for the candidate to face different interview styles.

I like to get people to talk about a project that they are proud of that that they felt particularly engaged with. If it's a hobby or a side project that's great, but if it something they did at work that's great too. If they're not proud or passionate about anything that's a bad sign. This kind of question is good for rapport building and will often put the candidate at ease so it's good to ask this question early in the interviewing process.
